I am trying to apply different pipeline configurations depending on the branch name, mainly with the use of the "discard old builds" option. Is there any documentation on this? Can this be done? i am thinking something like this:
pipeline {
agent any
options {
disableConcurrentBuilds()
if (env.BRANCH_NAME.contains('release-')) {
buildDiscarder(logRotator(numToKeepStr: '20', daysToKeepStr: '365'))
} else if (env.BRANCH_NAME == 'master') {
buildDiscarder(logRotator(numToKeepStr: '20', daysToKeepStr: '90'))
} else {
buildDiscarder(logRotator(numToKeepStr: '10', daysToKeepStr: '20'))
}
...
}
It's best to define options for buildDiscarder in the multibranch job file, there you can define your options per type of branch. The following link is shows a job file in yaml format, ours were in groovy format, but you'll get the picture:
Jenkins Specific Build Discarders per branch
Anything else is declared within the Jenkinsfile, like this example:
pipeline {
agent {
kubernetes {
defaultContainer 'app-cicd'
yamlFile 'app-jenkins/jobs/app-cicd-pipeline/cicd-build-k8s.yaml'
}
}
parameters {
string(name: 'NAME', defaultValue: 'lodger', description: 'Name for App deployment')
}
options {
ansiColor('xterm')
gitLabConnection("gitlab")
}
